Current Network Status
On April 28 -- The CENIC AARNet router in LA was rebooted at 2:00pm HST to
fix some issues. During the reboot, all SX traffic was rerouted via the 10G
paths through Oahu. Everything was back to normal by 2:40pm, no downtime
was experienced.

On May 23 -- Starting at about 10:00am, UH-ITS started the work to insert
CFHT at Waimea into the INET ring. Since both the INET and SX through CFHT
had to be taken down, Hilo traffic was rerouted over the microwave. It took
longer than the one-hour that was originally anticipated. However by the
early afternoon, CFHT was on the INET 10Gb path. Kanoa is happy with the HP
switch that he elected to use for the new 10Gb connection.

On June 17 (a Sunday) -- Starting ~4:30pm there was an extended power outage
in Waimea due to some kind of tornado-like wind storm. The 10Gb INET
connection between Hilo and Mauna Lani through CFHT was down. It turned out
that the new 10Gb equipment at CFHT was not yet put on the UPS. Fortunately,
the old SX extension that provided the connection between Hilo and Mauna Lani
through CFHT had been reconfigured to bypass CFHT on May 23 when CFHT became
part of the INET. The 10Gb connection was restored later by Kanoa when he
was able to get to CFHT to put the equipment on the UPS after the storm had
passed.

Brief Updates of the UH 10Gb Upgrade
On May 23, UH-ITS successfully inserted CFHT into the INET ring. In terms
of redundancy on the Big Island, we now have:

Two links that bypass the equipment at CFHT -- the old 1GE Oceanic SX
extension and a 1GE from HawaiiCC to Mauna Lani. The latter will eventually
be upgraded to 10GE.

The OC3 microwave from UH Hilo to Oahu through Lanai.

Sometime next year, there will be the new 10Gb path over the saddle that
will be extended to Hale Pohaku to provide a 10Gb path for the MK summit.
Oceanic is working on getting their fiber installed using the Hawaiian
Telcom poles along the Saddle Road.

Pui Hin distributed an updated network map that includes all the latest
upgrades.

Plans for 10Gb and IPv6 in Hilo
In April, Cisco released the first of the 4500-X family of 10Gb switches
with 32 x 10 Gb SFP/SFP+ ports. The 4500-X has many advantages over the
4900M, some of which are:

In view of the many advantages the 4500-X has over the 4900M and the fact
that the prices are comparable, Pui Hin suggested waiting for the 16-port
model scheduled to be released in the June to July time frame.

Pui Hin is planning on supporting IPV6 with the 10Gb deployment.
Observatories will have the option of whether or not to support it on their
networks. Previously, UH-ITS was having problems with the large number of
routes on smaller switches such as the Catalyst 3750. This problem has now
been solved by using OSPF's not-so-stubby area (NSSA). A NSSA is an area
that allows the import of external routes only from nearby areas. Also, as
with IPv4, observatories can elect to use static routes with IPv6. Pui Hin
distributed a handout with allocation of IPv6 addresses for each observatory
and the recommendation from UH-ITS on how to assign them.

Kanoa also shared with the group his experience with the 10Gb and IPv6
deployment with the group.

FY 02/03 Budget
There is not much change between last year's and this year's budgets. We
managed to reduce the cost per observatory by ~$400 by trimming down the
amount for a few items. The cost per observatory will be $6814 vs last
year's $7275.

Weather Display Station
There was a brief discussion of the weather display station at HP.

Next meeting
September 13th, Thursday, 10:30am at the CFHT Waimea facility.
